1. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

2. A client with AIDS has impaired gas exchange from a respiratory infection. Which assessment finding warrants immediate intervention by the nurse?

• A. Elevated temperature
• B. Generalized weakness
• C. Diminished lung sounds
• D. Pain when swallowing

Correct answer: D

Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.

3. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.

4. An older client is receiving an IV of 5% dextrose in 0.45% normal saline at 75 mL/hour. Which assessment finding indicates to the nurse that the client is developing a complication from this therapy?

• A. Capillary refill takes > 3 seconds.
• B. Episodes of vertigo and loss of balance.
• C. Average daily output of 1200 ml.
• D. Pulse rate of 110 beats/minute and dyspnea upon exertion.

Correct answer: D

Rationale: The correct answer is D. Tachycardia and dyspnea are signs of fluid overload, which is a potential complication of IV fluid therapy. Choices A, B, and C are not directly related to fluid overload and are not typical signs of complications associated with the IV fluid therapy being administered.

5. A community hit by a hurricane has suffered mass destruction and flooding. Several facilities are not functioning, and the area is contaminated with human excretions. The nurse is developing a plan of care for clients diagnosed with cholera after an outbreak. Which intervention has the highest priority?

• A. Administer prophylactic antibiotics as prescribed.
• B. Provide fluid and electrolyte replacement.
• C. Isolate all infectious diarrhea victims.
• D. Administer cholera vaccine.

Correct answer: B

Rationale: Providing fluid and electrolyte replacement is the highest priority to prevent dehydration and shock in clients with cholera. Administering prophylactic antibiotics may be necessary but is not the highest priority. Isolating infectious diarrhea victims is important for preventing the spread of infection, but addressing fluid and electrolyte imbalances takes precedence. Administering a cholera vaccine is preventive and not the immediate priority in treating clients already diagnosed with cholera.
